The author expresses tier sincere thanks to Prof. Dr. B. C h r i s t e n s e n, for his valuable councils.Number of the examined specimens: 16.Type-specimens: Holotype (F. 2 ) and Paratypes (P. 5) deposited in the Zoosvstematical Institute of the L.

Head pore at 0/1, dorsal pores bemnnitm with VII. Oolour: whitish. Setae straight, with distinct ental hook: (3 ) , 4  —2 : 4  —(4),2. Maximum lenght of setae: 50 p. Cutaneous glands arranged in 3 transverse rows per segment; the cells are usually big, and yellowish or brownish.Clitellum situated on N11—1/2 XIII; weakly developed. Glandular cells arranged in transverse rows.Brain 1 1/2 — 2 times as long as wide, rounded. Peptonephridia (Fig. 2 a) very long, wide at the beginning, further on slender, unbranched, tubular, wound into a tight coil at the level of the speratheca, the end of the peptonephridia extends to VI. (Hence, the peptonephridia are simi­lar to that of F. iud^oidesy). Body fluid contains sometimes numerous detached setae, sometimes not one single. Lymphocytes of two types, in accordance with the Fridericia type. Dorsal vessel originating in X I X -  XXIII. Blood: colourless. Nephridia and septal glands of characteristi­cally Fridericia type. Chloragogen cells are present commencing with segment VI.Seminal vesicle well developed, extending over IX —XI., brownish. Sperm funnel (Fig. 2 d) 3 times as long as wide, about as long as diameter of body. Collar distinct. Efferent duct long and narrow. Penial bulb large and compact. The middle part shows a more muscular, the margin a loose glandular structure (Fig. 2e). Spermatheca (Fig. 2 b) consits of an almost cylindrical ampulla with two sessile diverticula of irregular outline. The ampulla communicates separately with the dorsolateral region of the oesophagus. Ectal duct is rather short and stout, about 2 - 2  1/2 times as long as length of ampulla, with two large, very conspicuous sessile glands (Fig. 2 c) at the ectal orifice.Discussion: This new species differs from other Fridericia species, of which the spermatheca have two diverticula, by its characteristic peptonephridia.

Peptonephridia (Fig. 3 a) with a few short terminal or subterminal branches, and ending in VI. Lymphocytes are of two types, in accordance with the Fridericia type. Dorsal vessel originating in X X —XXIV.  Blood:colourless. Neph- ridia and septal glands of characteristically Fridericia type. Chlora- gogen cells present, commencing with segment V.Seminal vesicle well developed, extending over X —XII,  it causes the distinct brown colour of these segments. Sperm funnel (Fig. 3d) 3 - 4  times as long as wide. The lenght of sperm funnel somewhat shorter than the diameter of body. Collar distinct. Efferent duct long and narrow. Penial bulb large anil compact. Spermatheca (Fig. 3c) consists of an al­most cylindrical ampulla and two globular diverticula, which have short stalks. The ampulla has a large lumen (Which disappears successively in older specimens). The diverticula have a distinct chamber, which is con­nected with the lumen of ampulla by a duet. The latter is widened in the middle, forming a small chamber. The chamber and the cavity of the di­verticula are full of spermatozoa and are of an intensive brown colour. The ectal duct is long and devoid of glands at the ectal orifice. The con­nection of the ectal duct and the two diverticula to the ampulla is most characteristic, and differs from all species described till now. Namely, the ectal duct is connected with the ampulla from one side, the two diverti­cula, however, from the opposite side (Fig. 3b). The ampullae communi­cate separately with the dorsolateral region of the oesophagus.Discussion: This species differs from Fridericia acworrdi.s' N u r m i n- e n 1970, F. aia/a N i e l s e n  and C h r i s t e n s e n  1959, F. wiacidaia I s s e l  1904 F. coiMnda B r e t s c h e r  1902, F. ieydiyi (V e j d o v s k y) 1877, F. wayaa F r i e n d  1899, F. rcaaiac M ö l l e r  1971, F.
